Android 4.2 is a latest mobile operating system developed by Google. Developer mode can nicely be worked out without USB Debugging of a device.

The issue arises why Google kept the Android developer mode entry so obstinate? Maybe to keep newbie away tricky tech. To make smartphones more user-friendly Google may have kept these settings hidden.

In developer mode user can straight away Reboot the System, update SDcard, wipe data, Factory Reset, Wipe Cache Partition, do CPU Tests and get SIM Information etc. These are a critical operation for any smartphone and that's why kept on back side.

Google have made a slight trick to enable a device in Developer mode. The trick is quite simple but slightly invisible from many of our eyes. Let's see how it works.

Go to Notification panel on your device.

Tap Settings

Tap on About Phone, you will see list in which tap on "build number"

Here is the trick, tap as much as 7 times until you read "you are now a developer!"

After 3rd tap, an auto count will start saying "You are now "x" steps away from being a developer".

Go back and you will see a "Developer Options" menu just above the "About Phone"

Done!
